When I entered the Missionary Servants of the Most Blessed Trinity I was most interested in the part of our Community name that spoke of being a Missionary and a Servant. The Most Blessed Trinity ... not so much.
In 12 years of Catholic school I learned the basics and more, so of course I knew about the Trinity. Catholics begin and end prayers with the sign of the Cross and the words,"In the name of the Father and of the Son and of the Holy Spirit. Amen.
I also had to memorize the Baltimore Catechism which had this to say about the Trinity:
"In God there are three Divine Persons, really distinct, and equal in all things-the Father, the Son, and the Holy Ghost. The Father is God and the first Person of the Blessed Trinity. The Son is God and the second Person of the Blessed Trinity. The Holy Ghost is God and the third Person of the Blessed Trinity.
The Blessed Trinity is one God in three Divine Persons. The three Divine Persons are one and the same God, having one and the same Divine nature.
All very true today and always but what difference does it make?
For me the Trinity is at the center of all good actions of all that is good in humans today.
Pope Benedict XVI sums it up:
Thus we see the "God of relation", thus in the final instance we see "creative Love. Everything comes from love, tends towards love and moves impelled by love, though naturally with differing degrees of awareness and
"The strongest proof that we are made in the image and likeness of the Trinity is this: only love can make us happy, because we live in relation to others, we live to love and to be loved. Using an analogy taken from biology
we could say that the human beings carry in heir 'genomes' the profound traces of the Trinity, of God-Love", the Holy Father concluded.
